' 4 Claims. Cl. 114-435 a The present invention relates to a sectional floating marine platform.

It is among the objects of the present invention to provide a sectional floating marine platform in which a plurality of floating platforms maybe assembled, so as to form an aircraft carrier or other operating platform which will be stabilized against waveaction and at the same time be supported at a high level above the maximum. variation due to wave action in cold weather or in storm or gale weathe Another object is to provide a stabilized marine platform which may be made of varying lengths and which is equally suitable for civilian or naval utilization.

A further object isto provide a marine construction which will provide sectional floating platforms for carrying passengers or aircraft and which may be used to give varying lengths of ship or floating aircraft carrier structures depending upon the requirements. i Still another object -is to give a variable length of ship or floating platform construction in which various sections may be assembled or removed depending upon requirements and in which damage to any one section may be eliminated by removal of said section from the assembled whole without damage to the entire structure.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects it has been found most suitable according to one embodiment of the present invention to provide a platform supported by individual floating units with each of said floating units having a balanced or shock absorber supporting connection to the corners of the platform.

In one preferred embodiment of the present invention each platform is supported upon four independently mounted pontoons or boat sections which are connected by lever and spring or shock absorber members to the platform. Desirably, these pontoons are so assembled and connected to the main floating platform that the platforms will be maintained level regardless of wave or sea action with the pontoons or boat units being capable of up and down motion without change in the level or balance of the platform.

In the preferred form, a plurality of these platforms are provided which are readily connected together so that an assembled platform of any desired length may be formed for carrying passengers or for use of naval aircraft. Each floating pontoon or boat unit desirably is provided with independent propulsion or motor units which may be employed together or in selected fashion to give the desired propulsion effect.

Figure 1 is a top plan view of one form of floating unit according to the present invention showing four port-,- toons and a rectangular platform supported thereon;

Figure 2 is a side elevational view of the floating plat: form of Figure 1;

Figure 3 is an end elevational view;

Figure 4 is a top plan view of an alter-native arrange ment showing a double bifurcated lever arm connection;

Figure 5 is a top plan view of still another arrangement showing the coupling connections; and

Figure 6 is a side elevational view of the structure of Figure 5.

Referring to Figures 1 to 3 there is shown form A and the pontoons B.

These pontoons B are connected by lever arrange-. ment C and a hinge arrangement D to thebottom of the platform A.

Shock absorber arrangements E are also provided. The control tower F may be positioned at one side of the platform.

Referring specifically to Figs. 1 to 3, platform A may be rectangular or be offset and on the lower face thereof there may be depending brackets 11 which carry the pivot pins 12. The lever arms C are desirably of a clevis shape joined together at 13 and separating into two individual arms 14. I v

The arms 14 terminate in the. members '15 which have eyes fitting on the pivot rods or pins 12. The junction portion at "16 will have a receptacle for receiving the spring shock absorber unit E which will take up the move-I ment due to the wave and sea action and at the same time maintain the platform A in stabilized level condition; vEach boat unit or pontoon unit B may be provided with a propulsion unit '17.

Although one platform A is shown in Figure 1, it is obvious that a number can be connected together to form a floating platform of any desired length and size. Although four floating units B are shown supporting each rectangular platform A more pontoon sets may be supplied for each platform.

In the arrangement shown in Figure 4, each pontoon or boat support G is provided with the bifurcated arms H which have a junction at 35 with the boats G.

The platform I will have the downwardly depending brackets 36 which carry the pivot pin 37 and the arms H will have the eyes 38 engaging the rod 37.

Referring to the structure of Figures 5 and 6, the platthe plat form K will be supported from the boat units L by means of the levers M and the shock absorbers N. \As shown each lever arrangement M consists of an inverted U- shaped structure with the side arms 50 and the connecting arm 51. The connecting arm 51 swivels in the brackets 52 positioned on the lower side of the platform K. The arms 50 are pivotally connected at 53 to the lugs or cars 54 mounted upon the floating boat structures L.

The platforms K may be connected together by means of the bifurcated or olevised connection unit 56 on the end 57 of one platform and the eye 58 on the end 59 of the next platform. The pins or bolts 60 extending through the bifurcated elements 56 in the eyes 58 will form the junction. It is thus apparent that the applicant has provided a simple floating elevated platform construction which will give a stable platform in a seaway and which may be of varying lengths depending upon the number of sections which may be connected together. Various types of shock absorbers may be desired to maintain the platforms A, J and K level in spite of varying floating positions of the pontoons B, G and L. It will be noted in the embodiment shown that the shock absorbers E, 39 and N are of the spring type but they also may be of the air shock absorber type. The propulsion units indicated at 17 and 61 in Figs. 2 and 6 will suifice for driving the platform through the water.

While there has been herein described a preferred form of the invention, it .should be understood that the same may bealtered in details and in relative arrangement of parts within the scope of the appended claims.

The various sections K'may be locked together rigidly or have pivot connections 60, as shown. The platforms may have berths, cabins, and other passenger and crew quarters. The engine rooms and fuel storage facilities mayalso be included in the platforms. The springs N may include or be replaced by shock absorbers of the liquid or pneumatic type.

. Having now particularly described and ascertained the nature of the invention, and in what manner the same is to be performed.

" What is claimed is:

l. A sectional floating platform comprising an elevated platform, a plurality of floating pontoons supporting said platform, a plurality of levers and shock absorbers connected between the pontoons and said platform, and supporting said platform at a high elevation above sea level, said lever connections consisting of a plurality of rigidly connected upwardly separated arms pivotally mounted at their upper ends on the underside of the elevated platform and said shock absorbers consisting of coil springs extending substantially vertically between said pontoons and the bottom of said platform.
